Gonna hurt your wallets really bad, unless DTG decides to take on this tedious project, with up to date graphics, AI conductors, passengers with luggages, HEP, etc.... For instance, if I'm operating a Sliver route, I want my cafe car to have it's respective menu. Here's another example: This fits the Crescent and New Orleans routes. No more terrible, repetitive sounds using only 5 .wav files. We need serious sound (also graphics) overhaul. Correct sounds and volume levels from every step away and towards the diesel locomotive, and passenger cars, 360º. All types of possible sounds you would ever hear on the locos and amfleet cars, especially the brakes squealing, iron wheels rotating on iron tracks (sounds like Magneto's magnetic force!), dozens of varieties of the K-series horns- touch-sensitive, A library of 5,000 .wav files will certainly made a very realistic and satisfying train set to operate long distance. Potato chips!
